This is a great place to stay as the host and his sister are particularly helpful. His sister helped me sort out a reservation problem with another place by calling for me, and the host drove me down to the markets/near the BTS station each day. One thing to be aware is that in the event that you find there is no water, just send a message to the host and he will sort it out for you.
Very easy communication with the host here! Would definitely stay here again next time I'm in BKK.
